Fragile X syndrome (FXS) is the most common form of inherited intellectual disability. However, genetic testing protocols and genetic counseling guidelines for FXS are not yet established in mainland China. In the present study, we conducted a comprehensive analysis using a self-administered questionnaire among students at the Xiangya medical school to investigate their attitude towards genetic testing and counseling issues of FXS. We have gained a general understanding of the attitudes of medical students towards these FXS issues in China. This information is of immense importance to develop appropriate genetic tests and to train counselors for FXS. As the medical school students surveyed are prospective physicians who will be a part of the Chinese health system, our survey was focused on the basic knowledge of FXS, population-based FXS screening, confidentiality and reproductive options for mutation carriers. The study demonstrated that only less than one third of the participants had heard about FXS. 94.6 % of participants were in favor of FXS screening for women in their reproductive age who had a genetic history of FXS. Furthermore, only half of the participants would inform their families about their genetic status in case of positive test results, and more than half of the participants supported natural conception and prenatal diagnosis for FXS mutation carriers. Additional findings and research implications are also discussed. This survey targeting potential doctors provides important information for the development of FXS genetic test and counselor training for the Chinese health system. 相似文献

Fair and equitable allocation of donor organs in the USA is a daunting yet necessary task, which can mean the difference between life and death for patients on transplant waiting lists. This paper proposes a multi‐criterion decision‐making model using the analytic hierarchy process to allow for an allocation decision to be made on the basis of urgency, efficiency, benefit and equity. These four perspectives and objectives can be broken down into both quantitative and qualitative measures, which can be easily combined and weighted through group consensus. The proposed model overcomes the limitations of a single type of system, integrates the views of many organ allocation philosophies, improves the decision maker's ability to collaborate, helps justify the decision and reaches the optimal result. In addition, the proposed profile matrix allows decision makers to graphically trade off criteria against each other and to clearly articulate the decision rationale. Our computational study suggests that the proposed model not only satisfactorily serves the objectives of many constituents, but also remains noticeably robust under various criteria‐weight‐change scenarios. It improves stakeholder confidence in the organ allocation procedure, maximizes the usefulness of the organ and enhances welfare to society. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

More than 600,000 U.S. children are reported for physical abuse annually. Risk factors are proposed in the literature, but a comprehensive, national assessment of risk factors and support services has not been conducted. An analysis of national data from the National Child Abuse and Neglect Dataset revealed that domestic violence, parental alcohol and drug use, prior child abuse and neglect, public assistance receipt, and child behavior problems are associated with higher odds of substantiated physical abuse reports, compared to unsubstantiated reports. Most families, however, failed to receive relevant support services for any of these risk factors. Screening by physicians, child protection workers, and others for these risk factors could help identify children at increased risk for physical abuse and inform prevention efforts and support-service provision. 相似文献

This research investigated the relationship between false memories induced by two different paradigms (misinformation and Deese–Roediger–McDermott [DRM]). The misinformation effect refers to the phenomenon that a person’s recollection of a witnessed event can be altered after exposure to misleading information about the event. DRM false memory represents the intrusion of words that are semantically related but not actually presented in the study session. Subjects (N = 432) completed both misinformation and DRM false memory tests. Results showed a small but significant correlation (r = .12, p = .02) between the misinformation and DRM false memories. Furthermore, using signal detection theory, we found that the discrimination ability index (d′) was related to both the misinformation and DRM false memories (r = ?.12 and ?.13, p = .01), while the response bias was related only to DRM false memory (r = ?.46, p < .001). These results suggest that misinformation and DRM false memories generally involve different mechanisms and that their shared mechanism may involve the global discrimination ability. 相似文献

This study explores the relationship between strain and delinquency participation among Chinese adolescents. Using survey reports of over 1,700 middle-school students in Fuzhou, China, the study yielded results consistent with expectations. First, a significant relationship is observed between reports of overall strain and delinquency after controlling for common correlates. Further, adolescents in Fuzhou, China are more likely to engage in delinquency in response to strain over status achievement. Finally, whereas boys are more susceptible to status-related frustration, girls are more responsive to strain over physical well-being. These results are discussed in light of sociocultural expectations pertinent to adolescents in Mainland China. 相似文献

In this study we tested the effectiveness of a forgiveness intervention for young adults with insecure attachment to their mothers. Twenty-seven students from four universities in Taiwan were recruited and assigned to either a forgiveness intervention or an alternative treatment control group. Dependent measures were administered at pretest, posttest, and 8-week follow-up. Within-group analyses demonstrated the participants in the forgiveness intervention showed greater improvement on measures of attachment security, forgiveness, trait anxiety, hope, and self-esteem than the participants in the alternative treatment group. Effect sizes were in the medium to large range. Implications for research and practice with families are discussed. 相似文献

This paper aims to provide an overview of the family therapy in mainland China, by analyzing its development, current situation and future directions. The authors argue that the history of family therapy can be understood as three stages: introductory stage from 1985 to 1994, “blossoming” stage from 1995 to 2004, and “fast growing” stage from 2005 to present. In every stage, we can see clear differences in each of the following fields: training (including training programs in universities and workshops held by companies or institutes), academics (including research articles, professional books and conferences), and general public environment (including media and policies). We also outline the development of China’s first university system family therapy training program as an example and evidence of family therapy’s significant present and future development in mainland China. Based on this, we highlight some points for future improvement in family therapy in mainland China, including developing indigenous theories and practice models, reinforcing training and research programs in university systems, and improving accreditation standard for all family therapists. 相似文献
